Mark Webber says the new pit lane exit at the Korean International Circuit is not up to Formula One standards but doubts it will cause any issues now the drivers have experienced it in free practice.

The pit lane exit has been changed to skirt around the outside of the run-off of Turn 1 before joining the track after Turn 2, but as it heads into the run-off area from the pit lane the drivers have to deal with significant bumps. Webber said they would have to live with it this weekend but believes it needs work if a contract is agreed for the race to continue next year.

"It's not the standard that it should be, but there's not much we can do now," he said. "We know it [the bump] is there, but it's pretty special. We know it's there and I'm sure they'll improve it if we ever come back here again."

Webber said he still had to work on his set-up, which is being tailored towards overtaking because of his ten-place grid penalty following a third reprimand in Singapore.

"The balance is not great. It's more about understanding the tyres again. That's the biggest thing and it's about getting them working. We need to work on our short- and long-run balance because obviously I'm going to be out of position [on the grid]. So we need a car that will be strong in the first sector so I can get some overtaking done."
